Product details
Overview
DF2134FA20JV from Renesas Electronics is a 16-bit single-chip microcomputer in the H8S/2134 Group, featuring a 32-bit H8S/2000 CPU core, 128 KB on-chip flash memory (F-ZTAT™), and integrated peripherals including dual 14-bit PWM timers, 8-channel 10-bit ADC, dual 8-bit DACs, three SCI interfaces, dual watchdog timers, and a 16-bit free-running timer. It operates at up to 25 MHz with 5 V supply and targets embedded control in PC peripheral subsystems.
For engineers reviewing the DF2134FA20JV datasheet, DF2134FA20JV pinout, DF2134FA20JV application, or DF2134FA20JV equivalent, key selection considerations include its 80-pin TQFP package, absence of DTC/I²C/HIF modules (distinguishing it from H8S/2138), flash endurance (10,000 erase/write cycles), 10-year data retention, and support for single-power-supply in-system programming.
Technical Context
The DF2134FA20JV implements the H8S/2000 CPU core with sixteen 16-bit general-purpose registers and a 16-Mbyte linear address space. It executes basic instructions in one state and supports efficient C-language compilation.
Its peripheral set includes three independent serial communication interfaces (SCI) supporting UART and IrDA modes, dual 14-bit PWM timers (PWMX) with complementary output capability, and an 8-channel 10-bit successive-approximation ADC with sample-and-hold. The device lacks I²C, host interface (HIF), data transfer controller (DTC), and timer connection functions-features reserved for the higher-tier H8S/2138 Group.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HD64F2134AV | Mask ROM version (no flash); identical pinout, same peripheral set, but firmware fixed at manufacture. | Suitable only for high-volume, unchanging firmware deployments where reprogramming is unnecessary. | Select HD64F2134AV when cost sensitivity outweighs field-upgrade requirement and design is finalized. |
| H8S/2138F-ZTAT™ | Includes DTC, I²C, HIF, and timer connection; 128 KB flash; same 80-pin TQFP package. | Required for applications needing DMA offload, multi-master I²C sensor networks, or host interface co-processor roles. | Choose H8S/2138F-ZTAT™ when peripheral expansion-especially I²C or DTC-is mandatory; otherwise DF2134FA20JV offers optimal cost/performance balance. |
Compared with HD64F2134AV, DF2134FA20JV enables field firmware updates and prototype iteration; compared with H8S/2138F-ZTAT™, it reduces cost and complexity by omitting unused peripherals while retaining core timing, analog, and communication capabilities essential for keyboard, battery, and panel control.

FAQ
What is the maximum operating frequency of the DF2134FA20JV?
The DF2134FA20JV operates at a maximum frequency of 25 MHz when supplied with 4.5 V to 5.5 V. This speed is guaranteed across commercial temperature range (0°C to +70°C) and defines the upper limit for instruction execution rate, peripheral clock derivation, and real-time response latency in applications such as keyboard scanning and battery monitoring.
Does the DF2134FA20JV support in-system programming?
Yes, the DF2134FA20JV supports in-system programming via its 128 KB F-ZTAT™ flash memory. Programming requires only the standard 5 V supply-no external VPP voltage-and can be performed through the on-chip SCI interface or dedicated flash control registers, enabling firmware updates after PCB assembly without removing the DF2134FA20JV.
How many analog-to-digital converter channels does the DF2134FA20JV have?
The DF2134FA20JV integrates an 8-channel, 10-bit successive-approximation ADC with internal sample-and-hold and voltage reference. All eight analog inputs are accessible via dedicated pins (AN0–AN7), and the ADC supports software- and timer-triggered conversions-making it suitable for simultaneous monitoring of battery cell voltages, thermistors, and power rail levels.
What peripheral modules are excluded in the DF2134FA20JV compared to the H8S/2138 Group?
The DF2134FA20JV omits the data transfer controller (DTC), I²C bus interface (IIC), host interface (HIF), and timer connection functionality present in the H8S/2138 Group. These omissions reduce silicon area and cost while maintaining full compatibility with H8S/2134-specific applications like keyboard control and battery management where those features are unnecessary.
What is the flash memory endurance and data retention specification for the DF2134FA20JV?
The DF2134FA20JV's F-ZTAT™ flash memory is rated for 10,000 program/erase cycles minimum and guarantees 10 years of data retention under normal operating conditions (25°C). These specifications are validated per Renesas' flash memory characterization and apply across the full commercial temperature range without derating.
